The larval stage of the Chinese endemic antlion Bullanga florida (Navás, 1913) is described for the first time with biological notes. The wide distribution of B. florida in southern China is discussed under the context of habitat selection of the larvae. Meanwhile, comparing the adults and larvae between B. florida and Dendroleon esbenpeterseni Miller & Stange, 1999, extensive morphological similarities suggest that these two species may belong to a same genus.
